Activities Booking App Peek Raises More Cash, Inks a Deal With Yelp

Peek, a startup that lets people book tours and activities, is announcing a new round of funding as well as a partnership with reviews giant Yelp.

Founded in 2012, Peek is a central place where you can book everything from white water rafting to wine tastings to surfing lessons in locations around the world. The company, which counts Twitter and Square CEO Jack Dorsey and Alphabet Chairman Eric Schmidt as investors, also provides a booking software for tour and activity operators.

CEO and co-founder Ruzwana Bashir said that the company has quadrupled bookings since January, and has raised a new round of $10 million, bringing the company’s total funding haul to $18 million. Investors in the round include Trulia founder Pete Flint, David Bonderman (TPG founder, Board of Uber), Ray Lane (former President of Oracle) and Gigi Pritzker & Michael Pucker (owners of Hyatt Hotels).

The company has also inked a new deal with Yelp, which is going to start allowing people to book tours and activities directly through the reviews site. All activity operators who work with Peek will now have a “Book Now” button on their Yelp page. Peek already has activity-booking partnerships with Hawaiian Airlines and Virgin America.

Bashir said that the new funding will be used to expand its team and to build a second office in Utah.

And in an evolving market, Peek will need the help. The company already competes with RezGo and other booking companies. Meanwhile, hospitality giant Airbnb airbnb also allows hosts to offer tours and activities, and the company hopes to offer more add-on services for its millions of users in the future.
